Suggestion 1: I think that the track barriers should be less sensetive (like taller so that when you crash into them, you will not flip and only just lose speed and not ruin your entire run.) This upgrade will also add more possibilitys like wall hits, to make a turn more easily and it will also make the game easier for beginners.
Suggestion 2: I also found that when you flip, and your wheels hit the ground in a werid way, the car will then spin out of control, usually ruining your run.
I hope that you will fix these bugs and take my suggestions into consideration, I think that it will benefit the players in general. Thanks.😁
